What it detects

This rule detects bcdedit modifying boot load options to disable driver signature integrity checks, a prerequisite for loading unsigned or malicious kernel drivers. This was observed in the ReadText34 ransomware incident alongside bring-your-own-vulnerable-driver activity. Disabling integrity checks lets attackers load kernel-level tooling to tamper with security controls.
